If you aren't following the Iranian thing, you should be. Twitter has been a good asset for the opposition.
It seems that Iranian officials did indeed offer up a sham of an election. If they didn't, arresting the opposition didn't make their side look all that much brighter. Attempting to quell the information about the whole ordeal by cutting electricity to major cities doesn't bode well either.
For what it's worth, I think Ahmadinejad has lost his mind in all this. Hard to tell when that happened, though. His answers to "the tough questions" always seemed vague and non-answers to me. "Can you ensure the safety of your challenger?" "I love all the Iranian peoples and if they disobey the law when coming out of a sporting event at a stadium, they will be arrested, but I love them all even though I have to arrest them." (Now, I know I paraphrased the Amanpour interview, but the hopeychangy answer is just too "wtf?" to fully portray it.)
